Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583718, here are decompositions:

17 + 31583701 = 31583718
31 + 31583687 = 31583718
59 + 31583659 = 31583718
97 + 31583621 = 31583718
157 + 31583561 = 31583718
191 + 31583527 = 31583718
197 + 31583521 = 31583718
211 + 31583507 = 31583718

Showing the first eight; more decompositions exist.
